To @ZZ whom, t may concern.-

Be it known that I, LON LEVY, a citizen of the Republic of France,residing in Paris, France, have invented certain new and usefulImprovements in Processes of Pouring Metal Ingots, of which thefollowing is a specification.

This invention relates to the process of pou ring steel or other metalto form ingots.

Part of the cavities produced in forging large steel ingots result fromthe fact that during the pouring of the metal there is produced at thesurface a solid crust,lwhich is at times covered by liquid metal withoutbecoming fused again, and this chiefly at the sides and angles. Thisphenomenon is marked Vto a still greater extent when the steel containscertain metals-chromium, nickel, dac. In order to obviate this defect, Ihave devised a method of pouring in such a way as to cause the jet toreach all parts of the surface of the ingot. For this purpose I employthe arrangement shown in the accompanying drawings.

Figure l is a vertical transverse section. Fig. 2 is a verticallongitudinal mid-section. Fig. 3 is a plan. Fig. Il is a front elevationviewed in the same direction as Fig. 1. Fig. 5 is a partial plan of Fig.4. Fig. 6 includes a fragmentary enlargement of the extreme left-handend of Fig. 4E and beneath it a plan of the same parts shown in thisenlarged fragment.

An intermediate ladle C of small size, 3rovided with an outflow-hole B,is suspended under the ladle P, which receives the charge of metal fromthe furnace and which has an outflow-hole A, directing the metal intothe intermediate ladle C.

The small ladle C, mounted on trunnions O, hung from hangers ff andsteadied by ties e g, can by means of a hand-lever Z be oscillated,which by inclining the jet from B causes it to reach all parts of thesurface of the metal in the ingot-mold L in a direction transverse tothe section of the ingot. As the main ladle P is at the same time movedin a longitudinal direction by its carriage D moving on tracks, asusual, it is obvious that all parts of the metal surface can besuccessively reached during the pouring.

C indicates the extreme position of the intermediate ladle on the oneside. It `may swing to a corresponding position on the other side. Whenthe ladle C is moved to the pc- 5 sition C, the metal can be poureddirectly from the main ladleP into the ingot-mold L.

In order to enable the ladle to be swung to the position C,the ties e gare of peculiar construction. The upper end of the tie g, instead ofbeing permanently attached to the 6o carriage D, is formed with a hookh, Fig. 5, which takes partly around one of the upright bars t' of therailing. The tie e is made in two sections, of which the upper one c islinked to the lower and is formed at its end with a hook j, which hookspartly around a post/i', while the main tie-rod e is formed with a bend7u, capable of engaging with the same post c, as shown in Figs. 5 and 6.Ordinarily the tie-rod g is connected on its end by its 7o hook 7L andthe tie-rod e' is connected by its hooked. end j, as shown in Fig. 5;but when it is desired to swing the intermediate ladle to one side thehook 7L is disengaged, the hook j is also disengaged, and the tiercd eis75 pulled u p and its bend 7o hooked over the post t', as shown in Fig.6, thereby displacing the rods and ladle tothe positions shown in dottedlines in Fig. 4.

Instead of arranging a movable intermedi- 8o ate ladle between the mainladle and the ingot-mold I can attain the Vsame result by giving themain ladle an oscillating movement on its carriage in the transversedirection, while the carriage moves longitudinally.

I claim as my inventionl. The process of pouring molten metal to avoidformation of solid crusts imprisoned in the liquid metal, and consequentcavities in the forging, by directing the jet downwardly 9o andsuccessively back and forth over different portions of the lmetalsurface, substantially as set forth.

2. The process of pouring molten metal to avoid formation of solidcrusts imprisoned in 95 the liquid metal, and consequent cavities in theforging, by directing the jet downwardly and repeatedly from side toside and from end to end of the mold to cover all portions of thesurface of the ingot, substantially as Ico lset forth.

`In Witness whereof I have hereuntosigned my name in the presence of twosubscribing witnesses.
